| Outline of Final Research Achievements |
Actual composite structures are usually designed based on the results which are obtained by elemental tests such as push-out test. The slip strength in the elemental test depends significantly on the concrete confinements, such as friction force at the bottom, concrete covering, rebar, the size of concrete etc. Then, evaluating the slip strength of an actual structure should be evaluated by considering only the confinement factors in the real structure. In this paper, fracture mechanism of elemental test is clarified, and slip strength evaluation formula is proposed based on the fracture mechanism. On the other hand, the slip strength of composite girders is investigated and compared with that of elemental test. As result, it is concluded that the evaluation formula can be applicable to evaluate the slip strength of a composite girder.
